Abstract

A device designed for controlling and regulating an electro-pneumatic parking brake circuit includes a manual controller configured to actuate a parking brake via the electro-pneumatic parking brake circuit, the manual controller having a first circuit arrangement and a second circuit arrangement, the first circuit arrangement being a digital, bidirectional circuit arrangement and the second circuit arrangement being an analog circuit arrangement. The device further includes control electronics electrically connected to the manual controller. The first circuit arrangement is connected to the control electronics via a first connection cable and the second circuit arrangement is connected to the control electronics via a second connection cable. The first connection cable is a digital data transmission channel configured to enable a digital data transmission between the digital circuit arrangement and the control electronics. The second connection cable is an analog data transmission channel configured to enable an analog data transmission.
